 they can easily be caught and preseryed. The box may

 and a piece of thin wood set inside the box at an angle, 

 in such a manner, that the beetles can get into the box

 scale any big Ayooden box can be used after openings 

 haye been closed up with strips of wood, not paper, and 

 a few round holes may be bored in one of the sides into 

 which collecting tubes are fitted, or a box as described 

 above. 



Often a bait may be used with advantage, such as a 

 small piece of bad meat or fish. If this is placed in a 

 wide mouthed bottle, and the bottle is buried in the soil 

 up to its mouth it may be that in a day or two several 

 carrion beetles, attracted by the smell of the meat, go 

 inside but can not readily get out again. Very often, 

 however, ants prove a great nuisance by getting in as

Cattle and horse dung often harbour special beetles, such 

 as the Scaraba^idsD. A ready method of collecting these, 

 even the smallest species, is to throw the dung into a
